DIFFERENT TYPE OF WOOD
 
The characteristics of wood differ depending on the type of plant it is derived from and how long it has been dried for. 

SEASONING 

One of the most common mistakes people make is to burn green, non-seasoned wood. Green wood can contain up to 75% moisture, a figure that has a considerable effect on the calorific value of the wood, since part of the heat released is used to evaporate the water content and is then dispersed into the flue along with the water vapour produced. Wood for burning in a wood stove must first be seasoned for a period of about 18-24 months, so as to reduce its moisture content to 15-20%. 

 
    

HARDWOOD AND SOFTWOOD 

All wood can be divided into two categories: “hard” or “soft”, according to its weight in kg per cubic meter of wood.

Softwood, weighing approx. 300-350 kg/m³, includes spruce, pine, poplar, alder, chestnut and willow. It burns more rapidly, producing greater heat: this makes it ideal for starting the fire, although if used as the main fuel, the stove will require more frequent refilling.

Hardwood, weighing approx. 350-400 kg/m³, includes elm, oak, holm oak, beech and ash. It is generally denser and less resinous than softwoods; for this reason it burns more slowly, producing longer-lasting heat.
